Name: Amusement devices > Illusion or stage device > Illusion caused by abnormal interior building structure appearing normal
Description: Amusement device wherein the illusionary effect created by the device involves a person entering into the inner portion (e.g., a furnished room) of an apparently conventionally constructed architectural housing arrangement (i.e., a building); and the person either physically experiences (e.g., the person has difficulty walking across the floor of a room) or visually observes (e.g., the person observes water running uphill) an event or an occurrence that, in his mind, cannot be possible; whereby the person experiencing or observing the illusion is unaware that the construction of the housing arrangement has been modified or altered to create the illusion.
